Build a TypeScript array playground: accept a comma/space separated list of numbers and apply sort (asc/desc), filter (even/odd), map (double), reduce (sum) and dedupe operations, showing the result after each click.
Difficulty
Medium
Estimated Time
30 minutes
Acceptance Criteria
All seven operations work on randomized seeded inputs and print correct results in order; empty input does not crash the page (bonus); no console errors.
